“But some of the greatest achievements in philosophy could only be compared with taking up some books which seemed to belong together, and putting them on different shelves; nothing more being final about their positions than that they no longer lie side by side. The onlooker who doesn’t know the difficulty of the task might well think in such a case that nothing at all had been achieved.”

Austro-British philosopher

Ludwig Josef Johann Wittgenstein was an Austro-British philosopher associated with logic, the philosophy of mathematics, the philosophy of mind, and the philosophy of language. He is known for work that shaped twentieth-century philosophical debate, especially in these fields. His writing centers on how language works, how thought is expressed, and the foundations of reasoning and meaning.
